> All calling via SIP PSTN carrier.
> progressinband = yes
> directmedia =  yes
> prematuremedia  =  no
> Incoming call A is answered with progress
> Then bridged with progress to external call B
> Call is processed with audio OK
> But no further SIP processing in console and all SIP further signalling dies including OPTIONS packets.
> This looks like a deadlock but asterisk not compiled with DEBUG_THREADS so I attached gdb to asterisk pid and have attached a txt file.
